Of the many quarterback possibilities being discussed, the one Eagles fans will be paying close attention to involves Vick.
The veteran QB is due a $3 million bonus if he's still on the team come Feb. 6. As Chris Wesseling of NFL.com reported, if "the Eagles pick up the option, Vick likely will be asked to take a pay cut on the remaining $13.5 million salary. If Vick balks -- or if Kelly decides to go in a different direction at quarterback -- the Eagles could wind up shopping the 32-year-old once the league year begins March 13."

Either way, with Vick as a known commodity, and Kelly's expertise with the spread option attack, the quarterback position on the Eagles has taken center stage.

Here's a look at what they're saying about Kelly and his options at quarterback going into the NFL offseason:

• Sam Donnellon of the Daily News tracked down Ricky Santos, a former quarterback at New Hampshire, to find out more about the perception that Kelly needs a mobile quarterback in his system to be successful. (Hat tip to to Dan Graziano of ESPN.com for the link):

By the time Santos finished his career in 2007 - a Walter Payton Award tucked under his arm - everyone there was convinced of what Kelly has been telling Philadelphia since his hire. It's less about the feet than it is about the brain. It's less about the speed of a particular play than it is the speed with which several plays are executed.

"Ricky was molded in Chip's mind," New Hampshire AD Marty Scarano was saying in his office recently. "And he was the prototype for what you see now. Option read. Adequate passer. Not particularly fast, but smart and competitive.

"We scored a zillion points when Ricky was here." ...

[Ricky Santos elaborates] "In terms of overall athletic ability, I'm average," Santos was saying Tuesday from his home in Bellingham. "Average arm. Average speed. Above-average game management and vision of the field. I just had a knack for finding guys in open space. Understanding situations. But I wasn't very tall. Had a 4.8 40. I wasn't explosive in any sense of the word. I just found ways to make plays."

“The job of a quarterback is simple. He has to ‘let it happen, and not make it happen.’ We want to move forward. That is a concept you have to make your team understand. The cardinal sin at our place is the quarterback sack. We want the ball out of the quarterback’s hands in 1.5 seconds. That does not mean holding the ball until 2.5, waiting for someone to get open.” ...

Does anybody see how that possibly adds up to Michael Vick quarterbacking the Eagles in 2013? He is the antithesis of most of these Kelly statements. He holds the ball forever, waiting for someone to get open, always looking for the big play, always reluctant to settle. As a result, he gets sacked a lot and hit more than almost any quarterback playing the game.

• Don Banks of SI.com released his first mock draft of the year, and with that, the Eagles select ... Geno Smith? Here's what he says about Smith as Kelly's quarterback of the future:

Smith's talents aren't a perfect mesh for Kelly's up-tempo offense, but he's got enough mobility to get the job done, and his pocket-passing skills are NFL ready. We know quarterbacks get pushed up by need, but the Eagles defense needs so much help that Alabama cornerback Dee Milliner could be tough to pass on.

• Would former Florida State quarterback EJ Manuel be a quarterback target for the Eagles? Manuel said, if he was, he'd be successful in Kelly's system:

“I can do the read-option as far as making the read, throwing the bubble on the outside or doing the vertical game,” Manuel said. “We did a lot of that (in college). You have to have quick guys around you, and I did at Florida State.” ...

Manuel (6-foot-5, 237 pounds) said the Seminoles operated out of a no-huddle in about 70 percent of their games in 2012. He strived to get the ball snapped with roughly 14 seconds on the play clock to make adjustments at the line.

The team is not confirming or commenting on any new hires until the staff is complete, so we won't officially know Lazor's role until then. However, he was a QB himself at Cornell and has been a QB coach for the Seahawks under Mike Holmgren and the Redskins under Joe Gibbs. So it stands to reason he'll coach QBs here since it's assumed that Pat Shurmur will be the offensive coordinator ...

It's interesting that between Lazor and Shurmur, Kelly has added guys to his offensive staff with NFL experience and that aren't related to the spread offense. The speculation is that since Kelly is arguably the foremost authority on the spread, he's surrounding himself with pro style NFL guys and his offense will some type of hybrid of the two.

• Geoff Mosher of CSNPhilly.com writes that former Oregon Ducks quarterback Dennis Dixon will likely be added to the quarterback mix for Kelly and the Eagles:

So far, Kelly has yet to drop clues about the direction he’s headed in at the game’s most important position but the captain of Kelly’s spread offense attack probably won’t be an aging Michael Vick or vaguely mobile Nick Foles.

If Kelly plans to build an offense that not only fits his vision but also can compete from the get-go, he needs a quarterback that understands his scheme and has the skill set to flourish in it.

Nobody on the current roster fits that description, but all signs point to Kelly having his man by next week. There are strong indications that Kelly won’t waste too much time after the Super Bowl before reaching out to Ravens practice squad quarterback Dennis Dixon and bringing him to Philadelphia.
